ACOUSTIC HOOD WITH GLARE SHIELD Abstract of the Invention The device disclosed is a combination sound hood and glare suppressing visor for use on office machines such as typewriters, where it is necessary to contain machine operating noise and suppress acoustic sound levels while at the same time retaining visibility of the document being printed. The device is capable of movement away from the paper opening of the typewriter or office machine to allow access to the printing zone or printing region of the typewriter and, upon the removal of the device from the region of the printing zone, the glare shield is lowered or collapsed controllably to remove obstructions to operator access of the printing zone. As the sound hood is replaced over the paper aperture of the typewriter or printer, the glare shield is again erected to its preset position to suppress glare from overhead and back lighting illumination. The visor may be adjusted and preset by the operator to present substantially a line or edge view thereof, thereby minimizing the distraction to the operator. The sound hood may be pivotally raised to a vertical or past vertical position to give access to the printing element or the typing zone. As the hood itself is raised, the angle between the hood and the visor is reduced until it becomes substantially zero, at which point the visor is raised along with the hood and positioned out of the way leaning backward away from the operator. As the hood is repositioned over the opening of the top of the typewriter to contain the acoustic vibrations, the visor is again positioned in its preset position.
